Heart Medications That May Protect Your Brain and One to Watch Out For
As we continue to explore ways to protect our cognitive health as we age, a new study highlights the potential role of common heart medications in reducing dementia risk. While lifestyle changes like diet and exercise have long been recommended, this research suggests that certain medications could provide additional benefits. However, not all heart drugs are created equal, and one in particular might even increase the risk of dementia. Let’s take a closer look at these findings.
Diuretics
Diuretics, commonly known as water pills, are often used to manage blood pressure by helping the body eliminate excess fluid. The study indicates that these medications could also play a role in reducing dementia risk. Researchers suggest that diuretics might “exert antioxidant and neuroprotective effects” by preserving potassium or uric acid levels. This protective mechanism could contribute to the lower risk of dementia observed in those who use these drugs long-term.
Renin-Angiotensin System (RAS)-Acting Agents
RAS-acting agents are another class of drugs used to treat high blood pressure. According to the study, these medications may specifically help ward off Alzheimer’s disease by safeguarding certain brain mechanisms. The researchers noted, “We can see a clear link between long-term use—five years or more—of these drugs and reduced risk of dementia in older age.” This suggests that maintaining consistent use of these medications could be beneficial for cognitive health.
Cholesterol-Lowering Drugs
Cholesterol-lowering medications, such as statins, are known for their role in managing heart health. The study found that these drugs might also lower the risk of dementia by preventing plaque buildup in blood vessels, which can impede blood flow to the brain. The combination of cholesterol-lowering drugs and blood pressure medications was particularly effective, further reducing dementia risk. “Previous studies have focused on individual drugs and specific patient groups but in this study, we take a broader approach,” explained Alexandra Wennberg, PhD, co-lead study author.
Combination Therapy
The study highlights the benefits of using a combination of the aforementioned drugs. Individuals taking two to three different treatments experienced a significant reduction in dementia risk, with a decrease of 27 to 30 percent. This suggests that a multi-faceted approach to managing heart health could also support cognitive well-being.
Antiplatelet Drugs
While many heart medications show promise in reducing dementia risk, antiplatelet drugs, such as aspirin, may have the opposite effect. These medications are used to prevent strokes by stopping platelets from clumping together. However, the study found that they might increase the risk of microbleeds in the brain, which is linked to cognitive decline. People taking these drugs had a 13 to 25 percent higher risk of developing dementia.
This study sheds light on the complex relationship between heart medications and dementia risk. While certain drugs show promise in reducing the likelihood of cognitive decline, others may pose a risk. It’s important for individuals to consult with healthcare professionals to determine the best course of action for both heart and brain health.
